The instructions your model reads when the skill loads.
The Value Proposition Canvas (VPC) is the canonical Strategyzer tool for designing and testing the fit between what customers care about and what your product offers. It is the "zoom-in" companion to the Business Model Canvas, focused on the two most failure-prone blocks: Customer Segments and Value Propositions. Where the Business Model Canvas asks "is this a viable business?", the VPC asks "are we building something customers actually want?"
The canvas has two sides. The Customer Profile describes the customer's world in their language -- jobs they are trying to do, pains they experience, and gains they aspire to. The Value Map describes the product's response -- the products and services offered, the pain relievers they include, and the gain creators they enable. Fit is achieved when the Value Map mirrors the Customer Profile element-by-element. The method follows Alexander Osterwalder and Yves Pigneur's Value Proposition Design (2014).
Before building the canvas, confirm these inputs. If any is unknown or vague, ASK — do not assume:
Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.
